2 3 Claims.

This invention relates to new and useful improvements in a combinedenvelope and writing sheet.

More particularly the invention proposes an improved combined envelopeand writing sheet which when in an open condition appears littledifierent from a conventional writing sheet. However, it is providedwith certain innovations which makes it possible to fold and seal it ina novel manner. An envelope is not required. An improved feature of thearticle resides in the simple way in which it may be opened by thereceiver.

Still further the invention proposes a new and improved combinedenvelope and writing sheet as briefly explained which may bemanufactured and sold at a low cost.

. of said sheet after said bottom section is folded upon said topsection. These two longitudinal score lines or folds l2 and II divideoff or form a central section it and two side sections H, asclearlyshown in Fig. 3.

A line of perforations it extends transversely 4 across the top portionof the sheet II at a dis- For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to thefollowing description and accompanying drawings, and to the appendedclaims in which the various novel features of the invention are moreparticularly set forth.

In the accompanying drawing forming a material part of this disclosure-Fig. 1 is a perspective view of the combined envelope and writing sheetillustrated in, an opened up condition and viewed from the outer side.

Fig. 2 is a perspective view of the article shown in Fig. 1 viewed fromthe inner side.

Fig. 3 is a perspective view of the article partially folded.

Fig. 4 is a perspective view of the article in its completely folded andsealed condition.

Fig. 5 is a perspective view similar to Fig. 4 but illustrating thearticle in the process of being opened up.

Fig. 6 is a perspective view of a combinedenvelope and writing sheetconstructed in accordance with a modified form of this invention, thissheet being viewed from the outer side.

Fig. 'I is a fragmentary elevational view looking in the direction ofthe line 1-1 of Fig. 6 but illustrated with the top portion of the sheetbent down. a

Fig. 8 is a perspective view of the article shown in Fig. 6 in itscompletely closed and sealed condition.

The new and improved combined envelope and writing sheet in accordancewith that form of the invention disclosed in Figs. 1 to 5, includes arectangular sheet ll of paper having a transverse score line or fold IIa short distance below the center of its long dimension for guidingfolding tance beneath the top edge equal, or substantially equal, to thedistance that said transverse score line or fold II is offset from thecenter of the long dimension of'said sheet 'II for dividing off a topstrip portion II. This top strip portion I. has a central section andside sections 2| which are defined by said longitudinal score lines orfolds i2 and i2.

A tab 2: with adhesive material 2: upon its 'Adh'esive material 25 isdisposed upon the front face of the side section 2| of said top stripportion ll which is adjacent the tab 22. Additional adhesive 20- isdisposed upon the back face of the side section 2i of the top stripportion II which is remote from the tab 22. The top portion I! has theouter face of its central section it imprinted with a box 22 or otherindication for a postage stamp. .It is also imprinted with several guidelines 20 to facilitate the writing of a name and address. The tab 22 isprovided with a line of perforations 2| at its base for facilitatingtearing when required.

The operation and use of the combined envelope and writing sheet may beunderstood from the following:

The sheet ll is sold in its open condition. The purchaser may write aletter or other material upon the inside face. Then it mag be foldedalong the transverse fold or score line If: Next it is folded along thescore lines i2 and if as indicated in Fig. 3. The side sections I!should now be so placed that the adhesive materials 25 and 26 areadjacent each other. This permits pasting or sealing of the article. Theadhesive 22 on the tab 22 is sealed over the adjacent portion of thefolded article. when completely closed and sealed, it looks asillustrated in Fig. 4. In this condition it may be sent through themails. The receiver may open the article by tearing the right hand edgeportion along the line of perforations 3, a II. In this way the strip isisremoved. Then the tab 22 is torn along the perforation 30.. The sheetIII is now free to be opened up.

- In Figs. 6 to '8 inclusive, a modified form of the invention has beendisclosed which is very similar to the prior form'but distinguishing intwo ways.

In this form the sheet I is provided with several tabs 22 so that'thearticle may be securely sealed.

The sheet I0 is also provided with a top strip portion it which isdivided by a transverse score line or fold 34' into an outer section 3!and an inner section 36; The outer section 35 is provided with adhesive26 covering oneof the side sections ll of the sheet 10. The innersection It of-the strip portion I9 is provided with adhesive 2 coveringthe other section II of the sheet ll.

2. In a combined envelope writing sheet having a sheet of paper formedwith a transverse score line along which the sheet can be foldedsubstantially in half and spaced longitudinal score lines along whichthe sheet can be folded substantially in thirds after being folded inhalf, a strip'portion along one end of the sheet, a line of perforationsdividing said strip portion from the sheet. a score line dividing saidstrip portion into an inner section and an outer section and along whichsaid strip portion may be folded in half to superimpose said outersection on the In other respects this form of the invention is identicalto the prior form and like parts may be recognized by the same referencenumerals.

The operation and use of this form of the invention is substantiallyidentical to the prior form distinguishing in that the sheet 10 may befolded on the transverse score or fold line 34 so as to place theadhesive Hand 26 on opposite faces of the sheet I0 similar to thelocation of the corresponding adhesive in the prior form of theinvention. Now the sheet may be folded and sealed in the same way asbefore described. The advantage of the second form of the inventionresides in the fact that the adhesive and 20 is applied upon one face ofthe sheet l0. In the first form it was required to. be placed on twofaces.

While Ihave illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by United 1 States Letters Patent is:

1; In a combined envelope and writing sheet having a sheet of paperformed with a transverse score line along which the sheet can befoldedsubstantially in half and spaced longitudinal score lines alongwhich the sheet can be folded substantially in thirds after being foldedin half, a

inner face of said inner section, and spaced adhesive areas on the outerface of said strip section. one at the end of said outer section and theother at the opposite 'end of said inner section, whereby when the sheetis folded in half. said strip portion may be folded in half and thesheet may then be folded into thirdsto superimpose said adhesive areasto be used to seal the sheet folded, said line of perforations'and saidscore line of said strip portion being arranged parallel to eachother'and transverse of the sheet.

3. In a combined envelope and writing sheet having a, sheet of paperformed with a transverse score line along which the sheet can'be foldedstrip portion along one end of the sheet, a line may then be folded intothirds to superimpose said adhesive areas to be used to seal the sheetfolded.

substantially in half and spaced longitudinal score lines along whichthe sheet can be.-folded substantially in thirds after being folded inhalf, a strip portion along one end of the sheet, a line of perforationsdividing said strip portion from the sheet, a score line dividing saidstrip portion into an inner section and an outer section and along whichsaid strip portion may be folded in half to superimpose said outersection on the inner face of said inner section, and spaced adhesiveareas on the outerface of said strip section, one at the end of saidouter section and the other at the opposite end of said inner section,whereby when the sheet is folded in half, said strip portion may befolded in half and the sheet may then be folded into thirds tosuperimpose said adhesive areas'to be used to seal the sheet folded, andspaced sealing tabs formed along the side'of the sheet adjacent the endof said outer section formed with said one adhesive area.
